Investigation of size-dependent properties of sub-nanometer palladium clusters encapsulated within a polyamine dendrimer.

This study describes the first example of the investigation of electronic, geometric, and catalytic properties of Pd subnano metal clusters of Pd(4), Pd(8), and Pd(16) stabilized by poly(propylene imine) (PPI) dendrimers using XAFS and IR analyses. The relations among these properties are also discussed.
